Abstract: Presented herein are techniques for optimizing spectral efficiency in a network. One or more metrics of one or more wireless access points that enable one or more wireless client devices to connect to a wireless network are monitored. The one or more metrics reflect a level of client device activity. Based on the one or more metrics, the level of client device activity is determined to require a change in a number of the one or more wireless access points that are active to serve the one or more wireless client devices. The one or more wireless access points are activated or deactivated to improve a spectral efficiency of the wireless network.

Abstract: This technology allows time synchronization in wireless networks with mobile stations. A wireless network controller transmits instructions to access points (“APs”) within the wireless network to monitor transmissions for time synchronization. One or more second APs observe fine time measurement (“FTM”) exchanges between a first AP and a mobile station. A particular second AP determines whether to perform a time synchronization with the first AP based on the detection of the FTM exchange or a determination that the station is moving toward the second AP. For time synchronization, the second AP determines the time that the first AP transmitted the FTM exchange and the time of transmission from the first AP to the second AP. The second AP synchronizes a second AP clock to the summation of the time of the transmission of the FTM exchange and the time of transmission from the first AP to the second AP.

Abstract: Time Sensitive Networking (TSN) Quality of Service (QoS) in overlapped administrative domains may be provided. A first Access Point (AP) may detect at least a second AP in a Co-Channel Interference (CCI) range. A micro-transaction auction between the first AP and at least the second AP may be established, and the first AP may provide compensation to second AP to acquire an agreement, from the second AP, to forgo transmitting during an upcoming service period. Next, the first AP may schedule transmissions for the service period and then transmit in the service period without interference from the second AP.

Abstract: Wireless dynamic file exchange is provided by, in response to a triggering network condition occurring, initiating an exchange of a parameter file including non-layer two content via a 802.11 message, such as a Generic Advertisement Service (GAS) message between an access point (AP) and a station (STA) connected to the AP; and in response to determining that the exchange was unsuccessful, terminating a connection between the AP and the STA. The parameter file may be sent over several messages and update the parameters for a new session or an existing session. Devices that do not conform to the updated parameters may be disassociated from the AP and re-connect to receive and implement the updated parameters.

Abstract: Disclosed are systems, apparatuses, methods, computer readable medium, and circuits for defining, at a network controller, a standby mode for the AP, which includes a Wi-Fi subsystem and a host subsystem; determining, at the network controller, that the AP satisfies a predetermined criteria; and transmitting, from the network controller to the AP, a standby mode for the host subsystem and a power on mode for a Wi-Fi subsystem, wherein the standby mode includes instructions to cause a host central processing unit (CPU) of the host subsystem to enter sleep mode.

Abstract: The present technology provides for efficient re-association of a STA from a first Wi-Fi AP to a second Wi-Fi AP where the respective Wi-Fi APs utilize different security protocols. Since the association and key management (AKM) protocols are different and the cipher suites between generations of Wi-Fi technology, a STA normally would not be able to take advantage of the fast transition process. However, since the present technology allows the STA to derive the security keys in advance, the STA can perform the fast transition and efficiently roam to the Wi-Fi AP that utilizes a different association and key management (AKM) version.

Abstract: The automatic determination of components for Time Sensitive Networking (TSN), and more specifically the automatic determination of the Gate Duration (GD) and Guard Band (GB) for TSN may be provided. To determine the GB and/or GD for a TSN gate, a Time Error (TE) may be determined, and TSN components may be received. An Access Category (AC) and a per-AC Enhanced Distributed Channel Access (EDCA) state may be determined using the TID, wherein the per-AC EDCA includes a Contention Window (CW) minimum. Next, an Arbitration Interframe Space Number (AIFSN) of an upcoming data unit is determined using the using the AC and per-AC EDCA. The GB may be determined based on the AIFSN, the CW minimum, and the TE. The Gate Duration (GD) may be determined based on the TE and calculating a number of symbols in a MAC Protocol Data Unit (MPDU) and the upcoming data unit.

The preemption AC parameters may comprise a Contention Window maximum (CWmax) comprising a first predetermined value and a preemption Arbitrary Interframe Space Number (AIFSN) of less than or equal to a second predetermined value. AC parameters for others of the plurality of ACs may be received wherein a non-preemption AIFSN associated with any of the others of the plurality of ACs is greater than a sum of the first predetermined value the second predetermined value. Preemption for traffic in the preemption AC may be allowed.
